  • How to debug jQuery ajax POST to .NET webservice

    - by Nick
    Hey all. I have a web service that I have published locally. I wrote an HTML page to test the web service. The webservice is expecting a string that will be XML. When I debug the web service from within VS everything works great. I can use FireBug and see that my web service is indeed being hit by they AJAX call. After deploying the web service locally to IIS it does not appear to be working. I need to know the best way to trouble shoot this problem. My AJAX js looks like this: function postSummaryXml(data) { $.ajax({ type: 'POST', url: 'http://localhost/collection/services/datacollector.asmx/SaveSummaryDisplayData', data: { xml: data }, error: function(result) { alert(result); }, success: function(result) { alert(result); } }); The web method looks like so: [WebMethod] public string SaveSummaryDisplayData(string xml) { XmlDocument xmlDocument = new XmlDocument(); xmlDocument.LoadXml(xml); XmlParser parser = new XmlParser(xmlDocument); IModel repository = new Repository(); if(repository.AddRecord("TestData",parser.TestValues)) { return "true"; } return "false"; } } I added the return string to the web method in an attempt to ensure that the web-service is really hit from the ajax. The problem is this: In FF the 'Success' function is always called yet the result is always 'NULL'. And the web method does not appear to have worked (no data saved). In IE the 'Error' function is called and the response is server error: 500. I think (believe it or not) IE is giving me a more accurate indication that something is wrong but I cannnot determine what the issue is. Can someone please suggest how I should expose the specific server error message? Thanks for the help!

  • Inheritance using prototype / "new"

    - by mikkol
    Hi I'm new in Javascript OO and want to know more about about inheritance. Hope you can provide some advice! I see this great post: How to "properly" create a custom object in JavaScript? which talks about how a class is inherited as I see in other websites, ex.: function man(x) { this.x = x; this.y = 2; } man.prototype.name = "man"; man.prototype.two = function() { this.y = "two"; } function shawn() { man.apply(this, arguments); }; shawn.prototype = new man; The above post claims that in order not to call "man"'s constructor while inheriting, one can use a helper like this instead: function subclassOf(base) { _subclassOf.prototype= base.prototype; return new _subclassOf(); } function _subclassOf() {}; shawn.prototype = subclassOf(man); While I understand its intention, I don't see why we can't call shawn.prototype = man.prototype; I see it works exactly the same. Or is there something I'm missing? Thanks in advance!

  • Zend Framework: How to start PHPUnit testing Forms?

    - by Andrew
    I am having trouble getting my filters/validators to work correctly on my form, so I want to create a Unit test to verify that the data I am submitting to my form is being filtered and validated correctly. I started by auto-generating a PHPUnit test in Zend Studio, which gives me this: <?php require_once 'PHPUnit/Framework/TestCase.php'; /** * Form_Event test case. */ class Form_EventTest extends PHPUnit_Framework_TestCase { /** * @var Form_Event */ private $Form_Event; /** * Prepares the environment before running a test. */ protected function setUp () { parent::setUp(); // TODO Auto-generated Form_EventTest::setUp() $this->Form_Event = new Form_Event(/* parameters */); } /** * Cleans up the environment after running a test. */ protected function tearDown () { // TODO Auto-generated Form_EventTest::tearDown() $this->Form_Event = null; parent::tearDown(); } /** * Constructs the test case. */ public function __construct () { // TODO Auto-generated constructor } /** * Tests Form_Event->init() */ public function testInit () { // TODO Auto-generated Form_EventTest->testInit() $this->markTestIncomplete( "init test not implemented"); $this->Form_Event->init(/* parameters */); } /** * Tests Form_Event->getFormattedMessages() */ public function testGetFormattedMessages () { // TODO Auto-generated Form_EventTest->testGetFormattedMessages() $this->markTestIncomplete( "getFormattedMessages test not implemented"); $this->Form_Event->getFormattedMessages(/* parameters */); } } so then I open up terminal, navigate to the directory, and try to run the test: $ cd my_app/tests/unit/application/forms $ phpunit EventTest.php Fatal error: Class 'Form_Event' not found in .../tests/unit/application/forms/EventTest.php on line 19 So then I add a require_once at the top to include my Form class and try it again. Now it says it can't find another class. I include that one and try it again. Then it says it can't find another class, and another class, and so on. I have all of these dependencies on all these other Zend_Form classes. What should I do? How should I go about testing my Form to make sure my Validators and Filters are being attached correctly, and that it's doing what I expect it to do. Or am I thinking about this the wrong way?

  • Create Class functions on the fly?

    - by JasonS
    Hi, i have a validation class which needs improving. If I require some custom validation I need to specify a custom function. It works a bit like this: The controller tells the validation that a custom validation function is required. The controller runs the validation. --- Gets iffy here --- Validation class creates a new instance of the controller class.... Validation class runs controller-custom_validation_function() Validation class returns true / false Is there someway that I can alter this to do something like this? $validation = new validation; // Insert rules here. $validation-function() = $this-function(); By doing this I could get rid of the step of creating an unneeded class instance.

  • CakePHP 1.3 and Uploadifive/Uploadify - Change Upload Filename to a random string

    - by CaboONE
    I have somehow implemented UPLOADIFIVE in my CakePHP application. Everything seems to work great including uploading multiple files and inserting the correct information in the Database. Based on the following code, I would like to UPLOAD AND SAVE EVERY FILE WITH A RANDOM NAME TAKING INTO ACCOUNT THE CURRENT DATE OR SOMETHING SIMILAR. How could I accomplish this? In my Photos Controller I have the following function: // This function is called at every file upload. It uploads the file onto the server // and save the corresponding image name, etc, to the database table `photos`. function upload() { $uploadDir = '/img/uploads/photos/'; if (!empty($_FILES)) { debug($_FILES); $tempFile = $_FILES['Filedata']['tmp_name'][0]; $uploadDir = $_SERVER['DOCUMENT_ROOT'] . $uploadDir; $targetFile = $uploadDir . $_FILES['Filedata']['name'][0]; // Validate the file type $fileTypes = array('jpg', 'jpeg', 'gif', 'png'); // Allowed file extensions $fileParts = pathinfo($_FILES['Filedata']['name'][0]); // Validate the filetype if (in_array($fileParts['extension'], $fileTypes)) { // Save the file move_uploaded_file($tempFile,$targetFile); $_POST['image'] = $_FILES['Filedata']['name'][0]; $this->Photo->create(); if ($this->Photo->save($_POST)) { $this->Session->setFlash($targetFile, 'default', array('class' => 'alert_success')); $this->redirect(array('action' => 'index')); } } else { // The file type wasn't allowed //echo 'Invalid file type.'; $this->Session->setFlash(__('The photo could not be saved. Please, try again.', true)); } } } In my View file - admin_add.ctp I have added the following function $('#file_upload').uploadifive({ 'auto' : false, 'uploadScript' : '/photos/upload', 'buttonText' : 'BROWSE FILES', 'method' : 'post', 'onAddQueueItem' : function(file) { this.data('uploadifive').settings.formData = { 'photocategory_id' : $('#PhotoPhotocategoryId').val() }; } }); <input type="file" name="file_upload" id="file_upload" />

  • Best practices to develop and maintaing code for complex JQuery/JQueryUI based applications

    - by dafi
    I'm working on my first very complex JQuery based application. A single web page can contain hundreds of JQuery related code for example to JQueryUI dialogs. Now I want to organize code in separated files. For example I'm moving all initialization dialogs code $("#dialog-xxx").dialog({...}) in separated files and due to reuse I wrap them on single function call like dialogs.js function initDialog_1() { $("#dialog-1").dialog({}); } function initDialog_2() { $("#dialog-2").dialog({}); } This simplifies function code and make caller page clear $(function() { // do some init stuff initDialog_1(); initTooltip_2(); }); Is this the correct pattern? Are you using more efficient techniques? I know that splitting code in many js files introduces an ugly band-bandwidth usage so. Does exist some good practice or tool to 'join' files for production environments? I imagine some tool that does more work than simply minimize and/or compress JS code.

  • Ajax Upload using valums ajax upload plugin inside a form.

    - by idrish
    Hi , i just came across this ajax upload plugin and i wish to use it inside a form as shown in the demo page example 3. For some reason i am not able to make it work. I am not sure what parameters come into the function. For example here is my sample code. $(document).ready(function(){ var upload = new AjaxUpload('property_i', { action: 'submitproperty.php', autoSubmit: false, onSubmit : function(file , extension){ return false; } }); var upload_data = upload.setData({ 'propertytype':'propertytype' }); }); Now the ID used in the AjaxUpload function should be ID of the or of the Entire form. Also how do i use setData method. Any suggestions or links will be very helpful. Thanks

  • N-Tier Architecture - Structure with multiple projects in VB.NET

    - by focus.nz
    I would like some advice on the best approach to use in the following situation... I will have a Windows Application and a Web Application (presentation layers), these will both access a common business layer. The business layer will look at a configuration file to find the name of the dll (data layer) which it will create a reference to at runtime (is this the best approach?). The reason for creating the reference at runtime to the data access layer is because the application will interface with a different 3rd party accounting system depending on what the client is using. So I would have a separate data access layer to support each accounting system. These could be separate setup projects, each client would use one or the other, they wouldn't need to switch between the two. Projects: MyCompany.Common.dll - Contains interfaces, all other projects have a reference to this one. MyCompany.Windows.dll - Windows Forms Project, references MyCompany.Business.dll MyCompany.Web.dll - Website project, references MyCompany.Business.dll MyCompany.Busniess.dll - Business Layer, references MyCompany.Data.* (at runtime) MyCompany.Data.AccountingSys1.dll - Data layer for accounting system 1 MyCompany.Data.AccountingSys2.dll - Data layer for accounting system 2 The project MyCompany.Common.dll would contain all the interfaces, each other project would have a reference to this one. Public Interface ICompany ReadOnly Property Id() as Integer Property Name() as String Sub Save() End Interface Public Interface ICompanyFactory Function CreateCompany() as ICompany End Interface The project MyCompany.Data.AccountingSys1.dll and MyCompany.Data.AccountingSys2.dll would contain the classes like the following: Public Class Company Implements ICompany Protected _id As Integer Protected _name As String Public ReadOnly Property Id As Integer Implements MyCompany.Common.ICompany.Id Get Return _id End Get End Property Public Property Name As String Implements MyCompany.Common.ICompany.Name Get Return _name End Get Set(ByVal value as String) _name = value End Set End Property Public Sub Save() Implements MyCompany.Common.ICompany.Save Throw New NotImplementedException() End Sub End Class Public Class CompanyFactory Implements ICompanyFactory Public Function CreateCompany() As ICompany Implements MyCompany.Common.ICompanyFactory.CreateCompany Return New Company() End Function End Class The project MyCompany.Business.dll would provide the business rules and retrieve data form the data layer: Public Class Companies Public Shared Function CreateCompany() As ICompany Dim factory as New MyCompany.Data.CompanyFactory Return factory.CreateCompany() End Function End Class Any opinions/suggestions would be greatly appreciated.

  • jQuery: why does my live() handler declaration error out when the analogous click() one doesn't?

  • How can I make an AdvancedDataGrid re-display its labels when the results of the labelFunction chang

    - by Chris R
    I have an AdvancedDataGrid with a custom label function whose value can change based on other form status (specifically, there's a drop down to choose the time display format for some columns). Right now, I have this labelFunction: internal function formatColumnTime(item: Object, column: AdvancedDataGridColumn): String { var seconds: Number = item[column.dataField]; return timeFormat.selectedItem.labelFunction(seconds); } internal function formatTimeAsInterval(time: Number): String { if (isNaN(time)) return ""; var integerTime: int = Math.round(time); var seconds: int = integerTime % 60; integerTime = integerTime / 60; var minutes: int = integerTime % 60; var hours: int = integerTime / 60; return printf("%02d:%02d:%02d", hours, minutes, seconds); } internal function formatTimeAsFractions(time: Number): String { if (isNaN(time)) return ""; var hours: Number = time / 3600.0; return new String(Math.round(hours * 100) / 100); } ... and the timeFormat object is a combo box with items whose labelFunction attributes are formatTimeAsFractions and formatTimeAsInterval. The columns that have time formats have formatColumnTime as their labelFunction value, because extracting the seconds in that function and passing it in to the formatters made for a more testable app (IMHO). So, when the timeFormat.selectedItem value changes, I want to force my grid to re-calculate the labels of these colums. What method must I call on it? invalidateProperties() didn't work, so that's out.

  • Panning Image Using Javascript in ASP.Net Page Overflows Div

    - by Bob Mc
    I have an ASP.Net page that contains a <div> with an <img> tag within. The image is large so the <div> is set with a size of 500x500 pixels with overflow set to scroll. I'm attempting to add image panning using a click and drag on the image. However, every time I begin dragging the image escapes the boundary of the element and consumes the entire page. Here is example code that illustrates the problem: <%@ Page Language="VB" AutoEventWireup="false" CodeFile="Default.aspx.vb" Inherits="_Default" %> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head runat="server"> <title></title> </head> <body> <form id="form1" runat="server"> <div> <div id="divInnerDiv" style="overflow:scroll; width:500px; height:500px; cursor:move;"> <img id="imgTheImage" src="Page0001.jpg" border="0" /> </div> <script type="text/javascript"> document.onmousemove = mouseMove; document.onmouseup = mouseUp; var dragObject = null; var mouseOffset = null; function mouseCoords(ev){ if(ev.pageX || ev.pageY){ return {x:ev.pageX, y:ev.pageY}; } return { x:ev.clientX + document.body.scrollLeft - document.body.clientLeft, y:ev.clientY + document.body.scrollTop - document.body.clientTop }; } function getMouseOffset(target, ev){ ev = ev || window.event; var docPos = getPosition(target); var mousePos = mouseCoords(ev); return {x:mousePos.x - docPos.x, y:mousePos.y - docPos.y}; } function getPosition(e){ var left = 0; var top = 0; while (e.offsetParent){ left += e.offsetLeft; top += e.offsetTop; e = e.offsetParent; } left += e.offsetLeft; top += e.offsetTop; return {x:left, y:top}; } function mouseMove(ev) { ev = ev || window.event; var mousePos = mouseCoords(ev); if(dragObject){ dragObject.style.position = 'absolute'; dragObject.style.top = mousePos.y - mouseOffset.y; dragObject.style.left = mousePos.x - mouseOffset.x; return false; } } function mouseUp(){ dragObject = null; } function makeDraggable(item){ if(!item) return; item.onmousedown = function(ev){ dragObject = this; mouseOffset = getMouseOffset(this, ev); return false; } } makeDraggable(document.getElementById("imgTheImage")); </script> </div> </form> </body> </html> Also note that this HTML works fine in a non-ASP.Net page. Is there something in the ASP.Net Javascript that is causing this issue? Does anyone have a suggestion for panning a JPEG within a <div> block that will work in ASP.Net? I have tried using the jQueryUI library but the result is the same.

  • Add autoFill capabilities to jQuery-UI 1.8.1

Does anyone know how to extract the ID out of the autocomplete when you don't actually select the field?

  • Using AesCryptoServiceProvider in VB.NET

    - by Collegeman
    My problem is actually a bit more complicated than just how to use AES in VB.NET, since what I'm really trying to do is use AES in VB.NET from within a Java application across JACOB. But for now, what I need to focus on is the AES implementation itself. Here's my encryption code Public Function EncryptAES(ByVal toEncrypt As String, ByVal key As String) As Byte() Dim keyArray = Convert.FromBase64String(key) Dim toEncryptArray = Encoding.Unicode.GetBytes(toEncrypt) Dim aes = New AesCryptoServiceProvider aes.Key = keyArray aes.Mode = CipherMode.ECB aes.Padding = PaddingMode.ISO10126 Dim encryptor = aes.CreateEncryptor() Dim encrypted = encryptor.TransformFinalBlock(toEncryptArray, 0, toEncryptArray.Length) aes.Clear() Return encrypted End Function Once back in the Java code, I turn the byte array into a hexadecimal String. Now, to reverse the process, here's my decryption code Public Function DecryptAES(ByVal toDecrypt As String, ByVal key As String) As Byte() Dim keyArray = Convert.FromBase64String(key) Dim toDecryptArray = Convert.FromBase64String(toDecrypt) Dim aes = New AesCryptoServiceProvider aes.Key = keyArray aes.Mode = CipherMode.ECB aes.Padding = PaddingMode.ISO10126 Dim decryptor = aes.CreateDecryptor() Dim decrypted = decryptor.TransformFinalBlock(toDecryptArray, 0, toDecryptArray.Length) aes.Clear() Return decrypted End Function When I run the decryption code, I get the following error message Padding is invalid and cannot be removed.

  • Canvas context used but not updated on canvas

    - by John Doe
    I am developing an small html5 game, where I have the following code: if(object.blocks){ var blocks = object.blocks, that = this; each(blocks,function(index){ that.blocks.push(new Block(this[index])); }); } I receive an object with some configuration and instantiate blocks with it. It works fine, but the Block class has an method, called draw: this.draw = function (ctx){ if(ctx){ var colors = ['#FF0000','#FFFF00','#0000FF','#00FF00'], color = Math.round(Math.random() * colors.length-1); ctx.fillStyle = colors[color]; ctx.fillRect(this.x,this.y,this.width,this.height); } }; It was working before I moved it into the Block class, but now it draws nothing. This is the code that calls draw: render: function(ctx){ each(this.blocks,function(index){ this[index].draw(ctx); }); } The context comes from the html page, from the main canvas.

  • dojo.io.iframe erroring when uploading a file

    - by Grant Collins
    Hi, Hit an interesting problem today when trying to upload an image file < 2MB using dojo.io.iframe. My function to process the form is called, but before the form is posted to the server I am getting the following error: TypeError: ifd.getElementsByTagName("textarea")[0] is undefined My function that is used to action the post of the form is : function uploadnewlogo(){ var logoDiv = dojo.byId('userlogo'); var logoMsg = dojo.byId('uploadmesg'); //prep the io frame to send logo data. dojo.io.iframe.send({ url: "/users/profile/changelogo/", method: "post", handleAs: "text", form: dojo.byId('logoUploadFrm'), handle: function(data,ioArgs){ var response = dojo.fromJson(data); if(response.status == 'success'){ //first clear the image //dojo.style(logoDiv, "display", "none"); logoDiv.innerHTML = ""; //then we update the image logoDiv.innerHTML = response.image; }else if(response.status == 'error'){ logoMsg.innerHTML = data.mesg; }else{ logoMsg.innerHTML = '<div class="error">Whoops! We can not process your image.</div>'; } }, error: function(data, ioArgs){ logoMsg.innerHTML = '<div class="error">' + data + '</div>'; } }); } The form is very basic with just a File input component and a simple button that calls this bit of javascript and dojo. I've got very similar code in my application that uploads word/pdf documents and that doesn't error, but for some reason this does. Any ideas or pointers on what I should try to get this to work without errors? Oh I'm using php and Zend framework for the backend if that has anything to do with it, but I doubt it as it's not even hitting the server before it fails. Many thanks, Grant

  • Can I trigger PHP garbage collection to happen automatically if I have circular references?

    - by Beau Simensen
    I seem to recall a way to setup the __destruct for a class in such a way that it would ensure that circular references would be cleaned up as soon as the outside object falls out of scope. However, the simple test I built seems to indicate that this is not behaving as I had expected/hoped. Is there a way to setup my classes in such a way that PHP would clean them up correctly when the outermost object falls out of scope? I am not looking for alternate ways to write this code, I am looking for whether or not this can be done, and if so, how? I generally try to avoid these types of circular references where possible. class Bar { private $foo; public function __construct($foo) { $this->foo = $foo; } public function __destruct() { print "[destroying bar]\n"; unset($this->foo); } } class Foo { private $bar; public function __construct() { $this->bar = new Bar($this); } public function __destruct() { print "[destroying foo]\n"; unset($this->bar); } } function testGarbageCollection() { $foo = new Foo(); } for ( $i = 0; $i < 25; $i++ ) { echo memory_get_usage() . "\n"; testGarbageCollection(); } The output looks like this: 60440 61504 62036 62564 63092 63620 [ destroying foo ] [ destroying bar ] [ destroying foo ] [ destroying bar ] [ destroying foo ] [ destroying bar ] [ destroying foo ] [ destroying bar ] [ destroying foo ] [ destroying bar ] What I had hoped for: 60440 [ destorying foo ] [ destorying bar ] 60440 [ destorying foo ] [ destorying bar ] 60440 [ destorying foo ] [ destorying bar ] 60440 [ destorying foo ] [ destorying bar ] 60440 [ destorying foo ] [ destorying bar ] 60440 [ destorying foo ] [ destorying bar ]

  • Programming R/Sweave for proper \Sexpr output

    - by deoksu
    Hi I'm having a bit of a problem programming R for Sweave, and the #rstats twitter group often points here, so I thought I'd put this question to the SO crowd. I'm an analyst- not a programmer- so go easy on me my first post. Here's the problem: I am drafting a survey report in Sweave with R and would like to report the marginal returns in line using \Sexpr{}. For example, rather than saying: Only 14% of respondents said 'X'. I want to write the report like this: Only \Sexpr{p.mean(variable)}$\%$ of respondents said 'X'. The problem is that Sweave() converts the results of the expression in \Sexpr{} to a character string, which means that the output from expression in R and the output that appears in my document are different. For example, above I use the function 'p.mean': p.mean<- function (x) {options(digits=1) mmm<-weighted.mean(x, weight=weight, na.rm=T) print(100*mmm) } In R, the output looks like this: p.mean(variable) >14 but when I use \Sexpr{p.mean(variable)}, I get an unrounded character string (in this case: 13.5857142857143) in my document. I have tried to limit the output of my function to 'digits=1' in the global environment, in the function itself, and and in various commands. It only seems to contain what R prints, not the character transformation that is the result of the expression and which eventually prints in the LaTeX file. as.character(p.mean(variable)) >[1] 14 >[1] "13.5857142857143" Does anyone know what I can do to limit the digits printed in the LaTeX file, either by reprogramming the R function or with a setting in Sweave or \Sexpr{}? I'd greatly appreciate any help you can give. Thanks, David

  • JSON parse failed

    - by Mesut
    hello i haven an error abour ajax post success. after the success function i added code for lookin for errors ... else if (exception === 'parsererror') { alert('Requested JSON parse failed.'); ... on my php code: echo json_encode(array('msg' => $msg, 'myClass' => $class)); returns back after my function. i checked in firebug and it returns like, response like {"msg":"Kayd\u0131n\u0131z Ba\u015far\u0131l\u0131","myClass":"alert alert-success"} html like {"msg":"Kayd\u0131n\u0131z Ba\u015far\u0131l\u0131","myClass":"alert alert-success"} there is no json tab on firebug and on my ajax code if i comment the dataType: "json", my success function is working but i cant get the response.msg or response.myClass, if i dont comment it, success function is not working, here is the ajax code $.ajax({ type: "POST", url: "index.php?page=addItem&action=addItem&edit=true", data: dataString, success: function(response) { $("#message").html(response.msg); $("#message").addClass(response.myClass); $("#itemForm").fadeOut("slow"); window.setTimeout('location.href = "index.php?page=addItem"', 1000); } });

  • convert integer to a string in a given numeric base in python

    - by Mark Borgerding
    Python allows easy creation of an integer from a string of a given base via int(str,base). I want to perform the inverse: creation of a string from an integer. i.e. I want some function int2base(num,base) such that: int( int2base( X , BASE ) , BASE ) == X the function name/argument order is unimportant For any number X and base BASE that int() will accept. This is an easy function to write -- in fact easier than describing it in this question -- however, I feel like I must be missing something. I know about the functions bin,oct,hex; but I cannot use them for a few reasons: Those functions are not available on older versions of python with which I need compatibility (2.2) I want a general solution that can be called the same way for different bases I want to allow bases other than 2,8,16 Related Python elegant inverse function of int(string,base) Interger to base-x system using recursion in python Base 62 conversion in Python How to convert an integer to the shortest url-safe string in Python?

  • Python objects as userdata in ctypes callback functions

    - by flight
    The C function myfunc operates on a larger chunk of data. The results are returned in chunks to a callback function: int myfunc(const char *data, int (*callback)(char *result, void *userdata), void *userdata); Using ctypes, it's no big deal to call myfunc from Python code, and to have the results being returned to a Python callback function. This callback work fine. myfunc = mylib.myfunc myfunc.restype = c_int myfuncFUNCTYPE = CFUNCTYPE(STRING, c_void_p) myfunc.argtypes = [POINTER(c_char), callbackFUNCTYPE, c_void_p] def mycb(result, userdata): print result return True input="A large chunk of data." myfunc(input, myfuncFUNCTYPE(mycb), 0) But, is there any way to give a Python object (say a list) as userdata to the callback function? In order to store away the result chunks, I'd like to do e.g.: def mycb(result, userdata): userdata.append(result) userdata=[] But I have no idea how to cast the Python list to a c_void_p, so that it can be used in the call to myfunc. My current workaround is to implement a linked list as a ctypes structure, which is quite cumbersome.

  • Overriding Only Some Default Parameters in ActionScript

    - by TheDarkIn1978
    i have a function which has all optional arguments. is it possible to override a an argument of a function without supplying the first? in the code below, i'd like to keep most of the default arguments for the drawSprite function, and only override the last argument, which is the sprite's color. but how can i call the object? DrawSprite(0x00FF00) clearly will not work. //Main Class package { import DrawSprite; import flash.display.Sprite; public class Start extends Sprite { public function Start():void { var myRect:DrawSprite = new DrawSprite(0x00FF00) addChild(myRect); } } } //Draw Sprite Class package { import flash.display.Sprite; import flash.display.Graphics; public class DrawSprite extends Sprite { private static const DEFAULT_WIDTH:Number = 100; private static const DEFAULT_HEIGHT:Number = 200; private static const DEFAULT_COLOR:Number = 0x000000; public function DrawSprite(spriteWidth:Number = DEFAULT_WIDTH, spriteHeight:Number = DEFAULT_HEIGHT, spriteColor:Number = DEFAULT_COLOR):void { graphics.beginFill(spriteColor, 1.0); graphics.drawRect(0, 0, spriteWidth, spriteHeight); graphics.endFill(); } } }
